Full title and description

ISO 10525:1997 — Counterbalanced trucks handling freight containers of 6 m (20 ft) length and above — Additional stability tests. This International Standard specifies additional stability verification tests for counterbalanced lift trucks used to handle freight containers of 6 m (20 ft) length and longer.

Abstract

ISO 10525:1997 defines supplementary test methods and procedural requirements (in addition to ISO 1074) to verify the stability of counterbalanced fork‑lift trucks when handling long freight containers (6 m / 20 ft and above). The tests address operating conditions such as travel with elevated containers, mast tilt, and wind loading, and provide pass/fail criteria and test arrangements to ensure satisfactory stability under specified conditions.

Scope

This standard specifies additional tests to verify the stability of counterbalanced lift trucks when handling Series‑1 freight containers of 6 m (20 ft) length and above. It provides test arrangements and procedures that supplement ISO 1074 and applies to conditions including travel with the container at normal travelling height, travel with a partially elevated container (subject to specified limits), and operations subject to wind loading (the standard includes provisions for wind speed up to 12.2 m/s and guidance for higher wind speeds). It does not apply to suspended loads that may swing freely or to containers with a mobile centre of gravity.

Key topics and requirements

• Additional stability test methods for counterbalanced trucks handling long freight containers (tilting platform tests, fixed‑slope tests and other verification procedures).
• Conditions and setup requirements (truck ready for use, fuel/ballast levels, tyre pressures, mast and fork positions, load‑carrying attachments and marking).
• Wind loading considerations — tests defined for wind speeds up to 12.2 m/s with equations and guidance to derive alternative ratings for higher wind speeds.
• Specific provisions for travelling forward with the freight container leading and limitations on elevated load height when required for visibility and operator position.
• Normative references and relationship to ISO 1074 and other container and industrial truck standards.

Typical use and users

Used by manufacturers and test laboratories to verify and demonstrate the stability performance of counterbalanced lift trucks when specified to handle long freight containers. Typical users include industrial truck OEMs, safety and compliance engineers, certification bodies, end‑users operating container handling equipment (ports, intermodal terminals, large warehouses), and standards committees developing related safety and test standards.

Related standards

ISO 10525:1997 references and supplements ISO 1074 (Counterbalanced fork‑lift trucks — Stability tests) and cites relevant container specifications such as ISO 1496‑2. It is part of the ISO suite of industrial truck stability and safety standards and has been superseded/replaced in the ISO 22915 series (see ISO 22915‑9:2014 for the later treatment of related tests and requirements).

FAQ

Q: What is this standard?

A: ISO 10525:1997 is an International Standard that specified additional stability tests for counterbalanced trucks handling freight containers of 6 m (20 ft) length and above.

Q: What does it cover?

A: It covers supplementary test methods and procedural requirements (tilting platform, fixed slope and related verification procedures) to confirm satisfactory stability for counterbalanced trucks when handling long containers, including considerations for wind loading and partially elevated container travel.

Q: Who typically uses it?

A: Manufacturers, test laboratories, certification bodies, safety engineers, and operators involved in container handling (ports, terminals, large warehouses) use the standard for product verification and compliance testing.

Q: Is it current or superseded?

A: ISO 10525:1997 has been withdrawn and later work addressing similar test topics is contained in the ISO 22915 series (for example ISO 22915‑9:2014). Users should apply the current ISO standards in force for certification and compliance.

Q: Is it part of a series?

A: It is part of the family of ISO standards on industrial truck stability and safety; it supplements ISO 1074 and is related to other parts in the ISO 22915 / industrial trucks series.

Q: What are the key keywords?

A: Counterbalanced truck, freight container, 20 ft, stability tests, tilting platform, fixed slope, ISO 1074, wind loading, industrial trucks.
